SPECIFICATION forming part of Letters Patent No. 581,142, dated April20, 1897.

Application filed May 7, 1896. Serial No. 590,577. (No model.)

To all whom, it 77%01/ concern.-

Be it known that I, JOHANNES SCHU- MAOHER, a citizen of the UnitedStates, re-

' sition building-block m ade in accordance with my invention. Fig. 2 isa detail sectional View through a portion of the same.

This invention relates to anew and useful improvement in compositionbuilding blocks and columns; and it consists, generally stated, incovering a suitable skeleton framework with a concrete material,saidframework having means for the intimate attachment of saidcomposition material, comprising a metallic meshwork which is secured tothe framework by projections struck up therefrom, as will hereinafterappear. Other features of the invention reside in the construction,arrangement, and combination of the several parts, all as willhereinafter be more fully described, and afterward pointed out in theclaims.

In the drawings, A indicates a suitable framework, which may be of woodor any suitable material, but I prefer to form the same of angle-iron.This framework is built up in skeleton form in such shape as will makeit strong enough to withstand the contemplated strain, and if it is tobe a column it will of course be made in the proportions desired.

B indicates metallic lathing or wire mesh, which is secured to thisframework and to which the composition material adheres when applied. Asshown in the drawings, this meshwork is attached by having its loopedends passed over projections ct, struck up fro m the angle-iron, whichprojections are afterward bent outwardly and down to hold the meshworkfirmly in place. In the instance that the framework should be of woodthis meshwork can be secured by staples, as is usual.

0 indicates suitable braces for this skeleton framework, which may be ofany desired or approved form. 4

After the skeleton framework has been constructed, either in theposition it is desired that the block or column shall occupy whenfinished or in a shop, whence it may be transported to the place it isto occupy, a composition material of cement and sand or other knowningredients is plastered on the outside and given such shape as it isdesiredthe eX- terior shall have. This composition material is of courseapplied in a moist state and passes through the meshes of the lathing,whereby an intimate attachment is made for this coverlng.

I am aware that many minor changes in the construction, arrangement, andcombination of the several parts of my device may be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

Having thus described my invention, what I claim, anddesire to secure byLetters Patent of the United States, is-

1. The herein-described composition building block or columncomprisingthe combination with angle irons having projections struck up from theiredges, of a wire mesh which is secured to said angle-irons by having itsloops passed over said projections, said projections being bent downover the loops to secure them in place, and acomposition material;substantially as described.

2. The herein-described composition building block and column comprisinga skeleton frame made of angle-iron, wire mesh which is secured ,to saidangle-iron by means of projections struck up from the angle-irons,suitable bracing for said angle-irons, and a composition materialsubstantially as described.

In testimony whereof I hereunto affix my signature, in presence of twowitnesses, this 2d day of May, 1896.
